  1. Baltimore Tool Chisel Test Stand Baltimore Tool President: Harry McCarty Baltimore Tool Representative: Dennis Shewbridge Consultant: Peter Popper Team 3: Matt Mitch Marc Orgovan Joe Stephens Faculty Advisor: James Glancey Nate Cloud

  2. Mission Statement: ---The team will provide Baltimore Tool with an automated test stand to evaluate their chisels. • Baltimore Tool would like to test the effectiveness of newly created chisels. • The impact transferred by these chisels is unknown. • The test stand will examine the impact transferred and any reduction in noise.

  3. Critical functions of the test stand • The test stand needs to measure the impacts to failure of the sample • The device needs to measure the sound of the impact • The test stand must help in the promotion and sales of the newly designed chisels • The device must be marketable Constraints for the stand • Needs to be safe • Machine needs to stop (possibly by an operator) when the test piece is fractured • Needs to run on 110 volt power source • The test stand must be able to last at least 20,000 impacts

  4. Current Testing: Analysis of Hammer Swing Variables

  5. Critical Components of the Device ProjectedPrototype: • Hammer Swinging System • Securing of the Chisel • Securing of the Sample • Anvil • Base/Frame • Sound Meter • Impact Counter • Safety Shield (Not Pictured)

  6. Customer and their Wants

  7. Tests: Clamp Testing Impact Force Test (to determine the required impact force) Force Input Test (to find the required input force)

  8. Selection of Critical Component • This system is the most critical because it delivers the realistic motion and impact. • Two choices for hammer swinging devices remained after the first phase. • They were a pinned cylinder system and a cylinder slider system. • The pinned cylinder system was chosen.

  9. Wants and Associated MetricsWith Target Values
